How to service Exhaust Valve and Intake Valve seats and guides on Lexus ES300?

Due to the intricate nature of the task and the specific tools and equipment required, a professional should handle the servicing of the valves, valve seats, and valve guides, often referred to as a valve job. A home mechanic can undertake the removal and disassembly of the head(s), perform the initial cleaning and inspection, then reassemble and transport them to a dealer service department or an automotive machine shop for the actual service work. This inspection allows the mechanic to understand the condition of the head(s) and valvetrain components and to know what work and new parts are needed when dealing with an automotive machine shop. The dealer service department or automotive machine shop will then remove the valves and springs, recondition or replace the valves and valve seats, recondition the valve guides, check and replace the valve springs, spring retainers and keepers (if necessary), replace the valve seals with new ones, reassemble the valve components and ensure the installed spring height is correct. They will also resurface the cylinder head gasket surface if it's warped. After the valve job has been professionally done, the head(s) will be in a condition similar to new. When the heads are returned, they should be cleaned again before installation on the engine to remove any remaining metal particles and abrasive grit from the valve service or head resurfacing operations. If available, use compressed air to blow out all the oil holes and passages.

Lexus ES300 Exhaust Valve

The Lexus ES300 Exhaust Valve allows burnt gases to exit the cylinder very fast to ensure smooth power and fuel efficiency of the sedan. Working with one of the camshaft lobes via an overhead cam valvetrain, in many modern Lexus ES300 engines, each Exhaust Valve opens for the exhaust stroke, then strong springs snap it closed to seal compression for the next cycle. Earlier generations that shared the overhead valve layout still utilized lifters, pushrods, and rocker arms to push on each Exhaust Valve, but the objective remained the same, get the chamber clear of hot gases before fresh mix arrives. Differences between these two styles are based primarily on component placement, and the overhead cam design eliminates long pushrods, saving weight and enabling the Lexus powerplant to have freer revs. Regardless of style, sufficient spring pressure is applied to keep the valve from floating, a dangerous condition that can leave the Exhaust Valve hanging open and even coming in contact with pistons. Overheating is the chief enemy of any ES300 Exhaust Valve; a burned seat or face on any ES300 Exhaust Valve can cause misfires, rough idle, and poor mileage, making the proper clearance important to every Lexus ES300 driver.
